The two most basic types of communication are serial and parallel. They are so common that even the cabling bears the name serial cable and parallel cable. Since electricity behaves according to the laws of physics, it is impossible to get the electrical signal to go any faster. There are two ways to get the data from one place to the other faster. The first is to squish the data bits tighter together. The second way is to transmit more bits simultaneously.

When information is sent across one wire, one data bit at a time, its called serial. Every computer on the face of the earth has some form of serial communications connector on it, whether internally or externally. Most people are familliar with the 'D' shaped 9-pin connector on the back of thier computer. This is a serial connector. The typical 9-pin 'D' shaped connector on the back of your computer uses 2 loops of wire (1 in each direction) for data communication, plus additional wires to control the flow of information. However, in any given direction, data is still flowing over a single wire.

Instead of squishing bits together, bits are sent over more wires simultaneously. In the case of an 25-pin parallel port, you have eight data-carrying wires so that eight bits can be sent simultaneously. Because there are 8 wires to carry the data, the data finishes being transferred eight times faster than a serial connection.

...industry were busy creating their own version of the microcomputer which they hoped would find its way onto peoples desks at work and at home. Steve jobs and Stephen Wozniak sold their most prized possessions to create the Apple computer which became the worlds first true PC that could be used by all. Both the Altair and the Apple used the new microprocessor technology that Intel had pioneered and ignored. These processors were an integral part of the computers that would revolutionize our society and find their way into devices we take for granted today.
Today PC's and microprocessors influence many parts of our everyday life, take for example your car, your stereo, your microwave, even your cell phones. Almost 60% of homes now employ a desktop computer as an indispensable tool used for many parts of daily life. Where would communications be without computers, we would have no Internet, no satellite television, no email, and no instant long distance connections. As I mentioned before microprocessors are an integral part of today's automobiles, they control fuel usage, emission control, and idle speed among other things. Even small household appliances such as digital radios now use simple microprocessors to control them. Where would our military be without computers to direct fire, track the enemy, and produce satellite images? There is truly nothing that has affected our lives in last fifty years more than the microcomputer....

DESIGN OF 4 - BIT EXPANDABLE SHIFTER
Name: Chinh Minh Le
Due date: 09/17/2013
Operation date: 09/16/2013
Class: ITCS 3181,L
Fall 2013
I. Purpose:
The goal of this assignment is to design a 4-bit expandable shifter. Input two 4-bit D3D2D1D0, output is shift of inputs. They depend on right shift or left shift or non shift. All of things, we should begin from smallest elements, then after we develop it. So, in this assignment, I begin from smallest elements such as: XOR, 2-in AND, 2-in OR, and NOT gates. I take ownership of these components by making personal symbols of them from Motorola library, test them(create test data, and simulate) and store them in my personal library. I used these components to build an XOR and make ownership, test it, create a symbol for it. Next, I used these gates to design 2-bit var mux , test it and make symbol for it. Finally, I design 4-bit expandable shifter. We know that in 2-bit var nux, then depend on S0S1 that we have output equal with one of inputs. I this case, we have true table follow:
S0
S1

0

From 2-var mux we design 4-bit expandable by use 4 components of 2-var mux. We base on tables follow to design them:

...Microcomputer applications
Microcomputer application software is software that is applied, or put to use, to solve a particular problem or perfume a particular task using a personal computer application software may be either custom or packaged many large organizations pay programmers to write custom soft ware- software that is specifically tailored to ether needs. The average person is most likely to deal with packaged software –the software that is literally package in a container of some sort and sold in stores or catalogues holding the software and an instruction manual, also referred to as documentation.
There is great assortment of packaged software to help you with a variety of tasks – writing papers preparing budgets, drawing graphs, playing games and more the wonderful array of software available is what makes computer so useful
The collective set of business tasks is limited, and the number of general paths toward performing these tasks is limited too. Thus, the tasks and the software solutions fall, for the most part, into just s few categories that can be found in most business environments these major categories are word processing (including desktop publishing) spreadsheet,
Database management, graphics and communications.
Word processing software lets you create edit format, store and print text, it is the three words in the middle – edit format and store that make word processing different format and store that...

The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset. On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster CP by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely. (Glossary)
"Also known as the logic board, main board, or computer board, the motherboard is the computer's main board and in most cases holds all CPU, memory, and I/O functions or has expansion slots for them". (Kingston)
The motherboard is the most important part of your computer. It is also one of the most compared, critiqued, and reviewed pieces of hardware. Often, on the internet, you'll find reviews and debates over which board is best or which chipset is best. The chipset controls the system and its capabilities. It is the hub of all data transfer. It is a series of chips on the motherboard, easily identified as the largest chips on the board with the exception of the CPU. Chip sets are integrated,...

...TERM PAPER OF MICROPROCESSOR
ON
COMPUTER,MICROCOMPUTER AND MICROPROCESSOR
ABSTRACT
Microprocessors have evolved dramatically in the twelve years of their development by the implementation of large numbers of devices on single chips. Word widths have increased along with microprogramming capabilities, addressing capabilities, and trends toward single-chip computers. Only a year after the introduction of 4-bit processors came the 8-bit processor. Three years later, in 1974, 16-bit processors became the leading technology. The article compares architectures and operations of the TI 9900, Intel 8086, Zilog Z8000, Motorola 68000, and NSC 16032 16-bit microprocessors. The 32-bit processor was realized in 1981. General trends in architecture, technology, principles of operation, register organization, instruction set, memory organization, and performance are examined in the Bellmac-32A chip, the HP 32-bit processor, and the iAPX 432 processor chip set. With the development of advanced processors have come improvements and evolution of operating systems and processor communications. Multiprocessing and special-purpose processors have also improved computing technology. The processor technologies are illustrated by diagrams and compared in tables. A glossary of microprocessor terms is included.
